A study has reviewed initial Glasgow Coma Scale (GCS) score and toxicology screening in patients with blunt head trauma from a trauma database and found that changes in GCS score were significantly higher in the impaired group compared to those with negative drug screening (05). Deep coma in overdose of nordiazepam and oxazepam involving therapeutic index of less than 20 results from an unrecognized drug-drug interaction (16). Most often, the effect of the offending medication is relatively short-lived, and a full recovery may be expected within several days. Fukumoto T, Katada F, Sato S, Shibayama H, Murayama S, Fukutake T. A case of acute leukoencephalopathy induced by a combination of 5-fluorouracil and metronidazole [Article in Japanese]. Typically, when doctors induce a coma, its as a last resort in very serious, life-threatening situations. Several drugs can cause coma. Reported cases of coma mimicking brain death secondary to baclofen overdose have described a duration of coma of up to 7 days [3, 4]. A coma can result from complications of conditions such as diabetes or an infection, or from a traumatic incident involving a blow to the head or a lack of oxygen. overdose, many references indicate the half-life of baclofen is approximately 2-4 h, but in overdose, the duration of effect far exceeds the recommended five half-life calculation [3]. However, overdose of drugs not normally acting on the CNS (eg, propranolol) may also induce coma. A massive brain injury or brain tumor can be more difficult to treat, and can lead to a much longer or irreversible coma. He was at a party and had been in a back room with other people his friends did not know. It's weird because usually when you hear about people dying from fentanyl they usually just stop breathing or they pass out but I never heard of anyone getting a coma. A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle and does not initiate voluntary actions. Member. The vital signs of the patient may also reflect drug intoxication. The term coma, as defined in the classic work of Plum and Posner, is reserved for patients who are in a state of unarousable psychologic unresponsiveness (15). Patients who develop secondary cerebral injuries require therapy directed at the specific complication. Computational modelling clarifies the role of parietal and frontoparietal connectivity during anaesthetic-induced loss of consciousness. CNS downers reduce basal metabolism and heart rate while still slowing the heart rhythm and breathing. He had multiple bruises on his arms and legs, but no overt signs of trauma to his head. A case has been reported of hepatic coma due to hepatotoxicity of abiraterone acetate, a drug used for the treatment of castration-resistant prostate cancer (19). Atropine is used to reverse the effects of cholinergic excess. Location: Milwaukee, WI. Any focal neurologic signs should alert the clinician to a structural lesion, such as a stroke, which can occur as a complication of drug intoxication (eg, cocaine-induced vasculitis, heroin injection associated with bacterial endocarditis). Drug-induced hypertensive crisis and cardiac arrhythmias are associated with neurologic complications including a comatose state. Clues to the presence of a vascular event include the timing, which is usually sudden or rapidly progressive, with focal neurologic signs on examination. Parents need to be educated to the risks of prescription medications if accidentally ingested by a child, and childproof caps should be utilized. Coma rarely lasts more than a month and usually ends sooner. A drug-induced coma (alcohol, GHB, ketamine) in which the subject is fully unconscious strongly resembles general anesthesia. Various explanations have been given for valproic acid-induced coma, and some of these are: Overdose is more likely to occur in bipolar disorder where higher doses are used. Severe hyper- or hypothermia can cause coma. It's the slowing of brain function that is necessary to prevent damage that can be done by a lack of blood flow. Several cases of coma due to therapeutic use of valproic acid in epilepsy as well as to its overdose have been reported in literature. Intubation and hyperventilation may aid in this process. Tests might include: Without the oxygen and sugars it needs to function, the brain is unable to deliver the electrical signals needed to maintain breathing and organ function. Two syndromes occur after acute carbon monoxide poisoning: persistent neurologic sequelae and the interval form of CO poisoning. With concomitant ethanol ingestion, respiratory depression becomes much more dramatic, and patients may become comatose and require ventilatory support. The pathologic physiology of signs and symptoms of coma. A nursing home. Let's take a deeper look into this. Lisa Marie Presley, 54, died Thursday while hospitalized in critical condition after reportedly going into cardiac arrest. Depression of the cerebral cortex can lead to confusion and intellectual impairment. Rare instances of coma have been reported with selected drugs: cefepime, colloidal silver, lamotrigine, intranasal desmopressin with severe hyponatremia, chloroquine, baclofen, tramadol, acyclovir, primidone, bromide, and over-the-counter hypnotics. Methadone-induced hypoglycemia has been reported in patients with cancer receiving long-acting methadone for pain. J Neurol Sci 2018;392:137-8. CT and MR imaging findings in methanol intoxication manifesting with BI lateral severe basal ganglia and cerebral involvement. Elderly persons are more liable to suffer toxic effects of therapeutic drugs due to polypharmacy and overdose effects resulting from renal and hepatic impairment. Metronidazole. Induced emesis is contraindicated in a patient with a depressed level of consciousness, but gastric lavage may be performed if the patient has the airway secured with an endotracheal tube. According to Scientific American, putting someone into a drug-induced coma is not all that different than the anesthesiologic process that more than 60,000 people undergo every year prior to surgeries. A combination of therapies was used in this case, including lipid emulsion therapy, plasmapheresis, hemodialysis, continuous venovenous hemodialysis, and endoscopic intestinal decontamination. A study on patients presenting with drug-induced coma showed that emergency department physicians underestimate diagnoses of GHB intoxication based on clinical observations alone (17). These compounds can have muscarinic and nicotinic effects. The term "drug-induced encephalopathy" is used when the cause is use or abuse of therapeutic drugs as well as illicit or recreational drugs, but it may be secondary to other drug-induced disorders, such as hepatic encephalopathy, hypertensive encephalopathy, uremic encephalopathy, hyponatremia, and hypoglycemia ( 11 ). The purpose of a rapid detox is just that to have the patient detoxed, Dr. Castellon said. A coma is induced in patients who are at high risk of brain injury, either from physical trauma (as in the case of Giffords, who was shot in the head in 2011), a drug overdose, or a disease. Dr. Castellon also acknowledged that while a pain-free withdrawal may sound appealing at first there are too many possibilities for complications, as well as increased likelihood of relapse., How a Painless Detox May Increase Relapse Risks. Finally, as a diagnosis by exclusion, patients may have psychogenic unresponsiveness. The brain and heart are particularly vulnerable to carbon monoxide and, consequently, high-dose exposure may lead to myocardial ischemia and arrhythmia and to neurologic disturbances, including coma, seizures, and focal signs. Carbon monoxide, alone or in combination with smoke intoxication, is one of the major causes of poisoning injury and death worldwide; yet, CO intoxication is often overlooked because carbon monoxide is an odorless gas and induces various non-specific symptoms. This can lead to a hypoxic-anoxic injury (HAI). Pediatrics 2019;144(2):e02182690.**. Some dietary deficiencies may cause encephalopathy, most commonly thiamine deficiency in alcoholics. This is a popular euphoriant as are two of its precursors, gamma-butyrolactone and 1,4-butanediol. Gamma-hydroxybutyrate (GHB). Types of Overdose Medication Sedative Overdose Narcotics, barbiturates, and liquor are all sedative that damage the central nervous system due to overdose medication. Brain imaging to rule out a primary brain lesion. The Rhabdomyolysis was a direct result of the muscle damage from laying on a hard surface for hours. Indirect effect on the brain by drug-induced disorders of other systems. "It . Posts: 52. friend in an induced coma/ drug overdose. Every article is reviewed by our esteemed Editorial Board for accuracy and currency. Some cases of coma due to drug intoxication require simultaneous use of various approaches. Hyperammonemic encephalopathy may occur due to Krebs cycle inhibition or urea cycle deficiency following 5-fluorouracil infusion, but recovery of consciousness usually follows with proper management of hyperammonemia (03). Drug intoxication should be suspected in any patient presenting with extreme drowsiness and coma-altered mental state without another overt etiology. Hypotension and prolonged Q-T syndrome are the most common cardiovascular side effects, and these can be life threatening. Erdmann A, Werner D, Hugli O, Yersin B. Can emergency department clinicians diagnose gamma-hydroxybutyrate (GHB) intoxication based on clinical observations alone? He supervises the drug and alcohol detox process for patients at FHE Health and is well-versed in best practices for medically supervised withdrawal. Signs and symptoms can include: Comas can have multiple causes. There may be evidence of epistaxis, common with nasal ingestion of cocaine. Alcohol: combination with sedative-hypnotics Anesthetics: eg, propofol Direct effect from prolonged use or overdose of following drugs: - Anticholinergic drugs - Antipsychotics - Barbiturates - Benzodiazepines in combination with other CNS depressants - Cephalosporins - Cholinergic drugs - Lithium overdose - Metronidazole - Opioids - Sympatholytic drugs - Tricyclic antidepressants - Valproic acid - Vigabatrin, Secondary effect of other drug-induced adverse effects, - Drug-induced hypoglycemia, eg, insulin - Drugs-induced serotonin syndrome - Drug-induced diabetes insipidus with hyperosmolar coma - Drug-induced hyperosmolar non-ketotic diabetic coma: eg, prednisone - Drug-induced hepatic encephalopathy, eg, 5-fluorouracil - Drug-induced cerebrovascular disorders: cerebral vasculitis, cerebral hemorrhage - Drug-induced cardiovascular disorders - Drug-induced hyponatremia - Drug-induced renal disorders: uremic encephalopathy - Neuroleptic malignant syndrome, Poisons: eg, cyanide, carbon monoxide Recreational drugs and drug abuse, - MDMA (Ecstasy) - Gamma-hydroxybutyric acid - Methaqualone - Psychedelics, eg, LSD - Synthetic cannabinoids. The entire experience feels hazy because. What Else Makes Rapid Detox a Risky Gamble? Organophosphate poisoning can be treated with pralidoxime, which releases the toxin bound to acetylcholinesterase. Here's how it works: A patient arrives in the emergency room after an overdose, car accident or other trauma that caused extensive brain injury. Other drugs that can cause this syndrome include atropine, certain agents used for treatment of Parkinson disease, muscle relaxants, neuroleptics, and tricyclic antidepressants. Young males appear to be particularly susceptible to developing neuroleptic malignant syndrome, and other predisposing factors include dehydration, preexisting cognitive dysfunction, and high doses of higher potency neuroleptics (eg, haloperidol), especially when given as an intramuscular injection. The most common bloodborne pathogen identified was hepatitis C virus; 41 (37%) patients had a current or previous hepatitis C virus infection documented in the medical record . Sometimes a coma is induced in patients who are at high risk of brain injury from incidents such as physical trauma, drug overdose or life-threatening seizures. A similar syndrome can be seen with abrupt withdrawal of dopaminergic agents, such as levodopa or pramipexole, as well as atypical neuroleptics, such as clozapine and olanzapine. Benzodiazepines potentiate the effects of other CNS depressants. How much does a medically induced coma cost? Doctors sometime induce . The third stage involves progressive renal failure and death. It is helpful to keep in mind a few rules of classical neurology while investigating a patient with possible drug-induced coma. Coma is unresponsiveness from which the patient cannot be aroused and in which the patient's eyes remain closed.Impaired consciousness refers to similar, less severe disturbances of consciousness; these disturbances are not considered coma. Response by recovery after intravenous glucose indicates hypoglycemic coma, response to naloxone usually indicates opiate drug overdose, and response to flumazenil indicates benzodiazepine overdose. Therefore, the term coma due to drug intoxication is preferred when it is due to drug overdose, inappropriate use, or as an adverse reaction. Because many drugs that cause slow rhythms also depress myocardial function, patients who've overdosed on them will have marked hypotension. Drug Overdose Overview. This usually happens within 20 seconds after the heart stops beating. Oxford: Oxford University Press, 2019:1-86. Slowed or irregular breathing. The major site of action of the benzodiazepines is the reticular activating system; however, in high doses generalized cortical depression may occur, which contributes to stupor. A careful skin exam may reveal signs of venipuncture, suggesting self-injection of drugs, including heroin. If a person is in a coma because of drugs or alcohol or other non-medical causes, they need emergency medical treatment. The physical examination may also give clues to the possibility of drug use or intoxication. Agulnik A, Kelly DP, Bruccoleri R, et al. Such claims can be misleading and dangerous. Plum F, Posner JB. Basically the story goes that he got a drug-induced coma and was in a coma for like a week and then his mom just pulled the plug and he died. Benzodiazepines can cause decrease in cerebral blood flow and cerebral metabolism, the distribution of which correlates with density of benzodiazepine binding sites. Jain KK. What does the future hold for ex-AH? Rarely a comatose state may result. This causes delirium, tachycardia, hypertensive crisis, malignant hyperthermia, cardiac arrhythmia, myoclonus, seizures, myoglobinuria, shock, coma, and death. Medical induction is another cause of comas. It was determined that he had a cocaine-induced vasoconstriction syndrome, and he was admitted to the intensive care unit for supportive management. Ihalainen R, Gosseries O, Van de Steen F. How hot is the hot zone? An etiological classification of drug-induced coma is shown in Table 1. Raised intracranial pressure and papilledema is more likely in intracranial space-occupying lesions. It is associated with disturbances of neuronal function, membrane metabolism, and anaerobic energy metabolism, respectively. His serum toxicology screen was positive for opiates and the urine toxicology screen positive for opiates as well as cocaine. In the emergency department, the patient was stuporous and only briefly and minimally responsive to vigorous shaking and nail bed pressure. World Neurosurg 2020;135:e664-70.**. Acetaminophen level is often not included in standard toxicology screens, but if this drug is suspected based on the history, it should be specifically requested. The prognosis with most drug intoxications may be good if the patient is carefully supported with adequate critical care. Detoxification. Toxicology screen should be performed on serum and urine. Depends on cause: The outcome from coma depends on many things including the cause of the coma the duration of coma and how much brain damage has occurred. Neuropsychiatric sequelae in adolescents with acute synthetic cannabinoid toxicity. Pale or blue-tinged, clammy skin. Low serum carnitine levels may predispose patients to impairment of consciousness when treated with valproic acid. He was given naloxone 1 mg intravenously, resulting in a temporary mild improvement in his level of arousal. A case of fulminant hepatitis after administration of abiraterone acetate [Article in Japanese].
